We have a persistent problem with light bulbs failing much earlier than their projected lifespan would predict. GU10s seem to last about 12 weeks, tungstens about 10. And really irritatingly, the jolly expensive Megaman low energy compact fluorescents which I have used to replace a number of GU10s are blowing too - a projected 5 year lifespan has gone down to about 6 months. There is a known problem with AC frequency here (Gibraltar - British standards) - is that enough to cause these problems or should I be looking elsewhere and giving the Electricity Authority a hard time? Is there any way I can protect my lamps, other than changing every appropriate switch to a "soft start" dimmer (yes I know that most fluorescents can't be used with dimmers).
Some of the lighting circuits are extensions off the original, 15 year old wiring - they were done by a qualified and well recommended local electrician.
The worst of it is that I have sufficiently bad vertigo to dread changing a downlighter in a 9 ft ceiling.......
